Under Washington, D.C. law, extortion is defined primarily under D.C. Code § 22–3251. The legal elements of extortion include:

• A person obtains or attempts to obtain the property of another with that person's consent;
• The consent is induced by wrongful use of actual or threatened force or violence, or by a wrongful threat of economic injury; or
• The property is obtained under color or pretense of official right (i.e., abusing official power to obtain property).

The statute specifies two main ways extortion can occur:

1. By wrongful use or threat of force, violence, or economic injury to induce consent to transfer property.
2. By obtaining property under the guise of official authority.

The penalty for extortion in D.C. can be a fine (as set forth in § 22-3571.01), imprisonment for up to 10 years, or both.

In summary, the key legal elements of extortion under Washington, D.C. law are:

• Obtaining or attempting to obtain property from another person;
• The other person's consent is induced by wrongful threats or force, including threats of economic harm;
• Or the property is obtained under color of official right.

This aligns with the general understanding of extortion as obtaining property through coercion or wrongful threats, which may include threats of violence, economic harm, or abuse of official power.

Note: While this is specific to Washington, D.C., other jurisdictions like Washington State have their own definitions and degrees of extortion, but the D.C. law focuses on wrongful threats or abuse of official power to obtain property.
